For H-1B workers approaching the end of their sixth year in H-1B status, the path forward often hinges on the timing of their green card process. The American Competitiveness in the 21st Century Act (AC21) provides important exceptions that allow for H-1B status beyond the typical six-year cap. However, the rules can be complex—especially when a labor certification or I-140 petition hasn’t yet crossed the 365-day mark required under Section 106(a) of AC21.
This blog breaks down how beneficiaries can plan proactively and file strategically, even when the 365-day threshold has not yet been reached at the time of filing, but will be met by the requested start date of the H-1B extension.
1. Understanding the Fact Pattern: A Common Challenge
Consider this scenario:
- A foreign national is in valid H-1B status with Employer A, but that employer is shutting down.
- Employer B wants to file an H-1B transfer, and the employee is nearing the end of the sixth year of authorized stay.
- A PERM labor certification was filed, but 365 days have not yet passed.
- Because the green card process is still relatively recent, the employee is not yet eligible for a one-year extension under AC21 § 106(a).
In this case, the employer can only file for a transfer covering the remainder of the sixth year—unless an approved I-140 becomes available to support a three-year extension under AC21 § 104(c).
2. Timing and Filing Costs: Two-Stage Filing Dilemma
This scenario creates a logistical and financial burden:
- The first filing (I-129 transfer) must be made quickly to preserve status before the original employer shuts down.
- The second filing, once the PERM or I-140 has been pending for 365 days, becomes necessary to obtain any time beyond the sixth year.
Unless the I-140 is approved (via premium processing), allowing a three-year extension under § 104(c), there is no way to combine both steps in one petition—leading to double USCIS fees and legal costs.
3. Key Provision: AC21 § 106(a) Explained
Under AC21 § 106(a), an H-1B worker may receive one-year extensions beyond the six-year maximum if:
- A labor certification application or I-140 petition was filed at least 365 days before the requested start date of the H-1B extension, and
- The underlying green card process remains pending or undecided.
Extensions under § 106(a) are granted in one-year increments and may continue until a final adjudication of the labor cert, I-140, or I-485 application is reached.
4. Can You File Before 365 Days Have Passed? Yes — With a Caveat
A common point of confusion is whether the H-1B extension can be filed before the PERM or I-140 has aged 365 days.
According to USCIS guidance:
“The petitioner may file an H-1B extension request under §106(a) prior to the 365-day mark, as long as the requested start date of the H-1B is on or after the date when 365 days have passed since the PERM or I-140 filing.”

✅ Example:
- PERM filed: September 1, 2024
- H-1B petition filed: August 15, 2025
- Requested start date on I-129: September 2, 2025
➡ USCIS can approve the extension beyond the sixth year, because the requested start date is after the 365-day threshold.
⚠️ But — Status Gaps Are Fatal:
If there’s no valid H-1B time remaining to bridge the gap between filing and the start date, USCIS cannot grant the extension. The beneficiary must maintain continuous H-1B status until the new requested period begins. Otherwise, the case risks denial for lack of eligibility at time of adjudication.
5. What If the I-140 Gets Approved Before the Transfer?
If the I-140 is approved before the employer files the H-1B transfer, then AC21 § 104(c) becomes available. This provision allows:
- Three-year extensions of H-1B status,
- For beneficiaries with an approved I-140 but no available visa number due to backlogs,
- Regardless of whether the 365-day period has passed.
This option can eliminate the need for two separate filings—but hinges on premium processing speed and coordination between the old and new employer.
6. Strategic Takeaways for Employers and Attorneys
- You do not have to wait for the 365-day period to actually pass to file the petition—only the start date must be on or after that mark.
- File early if the client’s sixth-year cap is approaching, but carefully calculate the timeline so the 365-day threshold will be reached on the start date.
- Consider bridging the gap with remaining H-1B time, if any, to avoid falling out of status.
- Explore I-140 premium processing to potentially qualify under § 104(c) and avoid the dual-filing burden.
- Always document timelines clearly in the cover letter to support the legal basis for post-sixth-year eligibility.
Conclusion
The AC21 provisions under Sections 106(a) and 104(c) provide critical lifelines for H-1B holders facing green card delays—but only when interpreted and applied with precision. Employers must think ahead when the employee is nearing the sixth year and structure filings to align with USCIS policy.
By leveraging the start date exception under § 106(a), companies can preserve continuity of status and avoid unnecessary case duplications, while supporting long-term immigration goals for valued employees.
